OBJECTIVE:: Bleeding complications either spontaneously or post-operatively are very common in patients with haemophilia. Sometimes these bleeding complications remain unresponsive despite being on high dose of clotting factor replacement. The aim was to assess the role of endovascular embolization...

PMID: 26035080
J Phys Chem B. 2015 Jul 30;119(30):9949-58. doi: 10.1021/acs.jpcb.5b02091. Epub 2015 Jul 16.

We employ five π-conjugated model materials of different molecular shape-oligomers and cyclic structures-to investigate the extent of exciton self-trapping and torsional motion of the molecular framework following optical excitation. Our studies combine steady state and transient fluorescence spectroscopy in...

OBJECTIVE:: To evaluate the usefulness of diffusion-weighted MRI (DWI) for the assessment of the intraindividual follow-up in patients with chronic periaortitis (CP) under medication.METHODS:: MRI data of 21 consecutive patients with newly diagnosed untreated disease were retrospectively examined before...

Perspective: Structure and ultrafast dynamics of biomolecular hydration shells.

Structural dynamics (Melville, N.Y.)

Laage D, Elsaesser T, Hynes JT.
PMID: 28470026
Struct Dyn. 2017 Apr 20;4(4):044018. doi: 10.1063/1.4981019. eCollection 2017 Jul.

The structure and function of biomolecules can be strongly influenced by their hydration shells. A key challenge is thus to determine the extent to which these shells differ from bulk water, since the structural fluctuations and molecular excitations of...

Thoracic aortic aneurysm develops as a result of complex series of events that alter the cellular structure and the composition of the extracellular matrix of the aortic wall. The purpose of the present work was to study the cellular...

Multiple relaxation pathways in push-pull polyenes.

Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology

Laage D, Plaza P, Blanchard-Desce M, Martin MM.
PMID: 12659165
Photochem Photobiol Sci. 2002 Jul;1(7):526-35. doi: 10.1039/b203201p.

Subpicosecond absorption and gain spectroscopy are used to investigate the excited-state behavior of push-pull polyenes made of a diethylthiobarbituric acid electron-acceptor group and a dibutylaniline electron-donor group linked by a pi-conjugated chain. Four polyenes of increasing length, ranging from...

[Physical activity and clustering of CVD risk factors--secondary publication].

Ugeskrift for laeger
